Pseudotsuga is a genus of large evergreen coniferous tree species, commonly known names are; Douglas-fir, Oregon pine, Douglas tree, and Douglas fir. There are 2 species native to western North America and four in eastern Asia (three Chinese and one Japanese), see table of tree names below.

History of the tree name;

The common name "Douglas-fir" honors David Douglas, the Scottish botanist who first introduced Pseudotsuga menziesii to Scotland in 1827. The hyphen in the name indicates that Douglas-firs are not true Firs, only that they look like Firs and were once classified with them (Genus Abies).

In the past these species of trees have been botanically classified in the genera groups of other trees of similar appearance such as in genus; Abies, Pinus, Picea, Sequoia, and Tsuga. These species were eventually classified into their own genera group by the French botanist Carrière in 1867, he grouped them by using their distinctive cones, and called the genera group "Pseudotsuga" meaning "False Hemlock". The genus name is also accepted as a hyphenated name; Pseudo-tsuga.

Douglas-fir Uses;

Douglas-fir (specifically Pseudotsuga menziesii ) is one of the most commonly marketed Live Christmas tree species in the United States.

Douglas-fir or Oregon pine wood is used extensively in the construction industry, especially for structural purposes that are required to withstand heavy transverse loads. Coast Douglas-fir, or Oregon pine (Pseudotsuga menziesii var. menziesii) is used in boat building when it is available in long, knot-free lengths. This wood was also used in boat mast building due to its ability to resist bending transverse loads without fracturing. Native Coast Douglas-fir, or Oregon pine is much heavier per unit than Sitka spruce, and Western Red Cedar (Thuja plicata).

Douglas-fir trees are also used as popular Landscaping trees especially in the northern United States, with may Cultivars of Pseudotsuga menziesii available such as; 'El Dorado', 'Fastigiata', 'Glauca Pendula', 'Graceful Grace', 'Hess Select Blue', 'Pendula', 'Seattle Mountain', 'Skyline', and 'Torquis'.
